July 7th: The next morning we left for Silver Lake State Park (GPS: 9679 State Park Rd, Mears, MI 49436) Here you can climb up the sand dunes and also perform activities such as: Water Sports - Jet Ski Driving up and down the sand dunes by renting an ATV or if you have a 4WD Here I choose to rent an ATV and climb up and down the dunes since that was something which I had never done or experienced earlier....
